Wind Energy Overview
Wind energy is tapped from the natural movement of the air, according to the National Center for Policy Analysis "Alternative Energy Overview." A wind turbine is the most common form to capture wind energy. The turbine's process is similar to solar power. The wind, a direct current, travels to an inverter. The inverter converts to AC (alternating current) for local use or use throughout the utility grid.

Modern wind turbines range in size, style and vary in production capability. The St. Louis County Government Services Center in Duluth, Minn., has roof mounted wind turbines, installed by APi Electric. The turbines collectively produce up to 6,000 watts of power.
The wind turbines installed for Minnesota Power's Taconite Ridge Wind Energy Center in Mountain Iron, Minn., stand at a massive 265 feet tall. The diameter of the spinning blades, 315 feet, is greater than the length of a football field. In ideal wind conditions, the 10 turbines can collectively capture the wind and convert it into 25 megawatts of electricity - enough to power 8,000 homes annually. The Taconite Ridge Operations Center is pursuing a LEED Silver certification.
There are very few companies that have done wind turbines, however, APi Group is experienced in wind and well versed with the capabilities to build and service many forms of alternative energy.
